OMER FRANQOIS LEFEBVRE, or MONTREAL, QUEBEC, CA ADA STAMP on PRINTING ROLLER. FOR STAMP canonrrivs MACHINES r Original application filed June 22, 1928, Serial No. 287,514. Divided 1929. Serial No. 378,498.

The present invention relates to improvements in stamp or printing rollers for stamp canceling machines, and is a divisional application of United States application Serial Number 287 ,514; filed June 22nd, 1928. It consists of a detachable wheel having a plurality of removable stamp units; means to automatically lock said units in position; and means for ejecting said units.

The main object of this invention is to provide a printing roller of simple construction provided with means for readily removing same from the canceling machine and quick- 1y changing the stamp units carrying the date, month and other desired information.

The invention is hereinafter fully de scribed and claimed and is illustrated in the accompanying drawings, in which Figure 1 is a side elevation view of a printing roller according to the invention;

Figure 2 is a vertical section view on line 22 of Figure 1;

Figure 3 is a top view of the roller, the cover having been removed;

Figure 4 is a cross section on line 4-4: of Figure 1.

Like numerals of reference indicate corresponding parts in each figure; 1 designates the circular top wall of the roller, 2 the bottom wall and 3 the side wall. One side of the said roller is flattened and provided with opening 4, and '5 are one or more openings in the side of the side wall 3, in which are located the removable stamp units 6 and 7.

The stamp-units are mountedin one or more suitable sockets 8, which register with the openings in the side wall 3, said socket or sockets being provided in a tubular supporting member 9, one end 10 of which is suitably threaded to receive the screw 11 of the handle 12, which projects outward of the top wall and locks the supporting mem her 9 in position. The said supporting member 9 has a circular flat lower end 13 which rests upon the bottom wall and a flanged central hole 14, which engages in the flanged hole 15 provided in said bottom wall, and 16 is a ember 18 that locks the revolving shaft 19 slot or opening in which engages the key upon which the said roller is mounted and is actuated thereby. i

;The opening is preferably closed by a door plate -20, which is hinged at 21'and spring held at 22. When said door plate is closed, a lug 23 secured thereto engages a corresponding recess 21, provided in theside of the stamp-units, thereby locking said stamp-units in place. WVhen: the door plate isopened, the free end engages in a suitable recess 25 in the supporting member 9 and the lug 23Vis disengaged from the recess 24, thus unlocking the said stamp units, and simultaneously, a lug 26, located adjacent said lug 23, engages the rear-end of the stamp-units andpushes same outward, so that they may be. readily removed, to change the dates or other suitable information.

Upon one side of said supportin 9, is provided a plate '27 having ah tion 28 adapted to engage a recess 29 in one of the stamp-units. This stamp-unit may readily be removed, after the adjacent stampunit has been removed. The stamp-unit 30 member which bears such information as the year, i

may be fixed by any suitable means (not shown), as this unit is only changed from year to year, and therefore does not require fastening means that is quickly unlocked.

It must readily be understood that the stamp-units may be ejected or simply moved outward, and that the expressions ejected and moved outward, are used to describe the action of pressing or pushing the stamp-units, entirely or not out oftheir respective sockets. It must also be mentioned that it is desired to cover in the present application both the locking and unlocking actions separately from the ejecting action. In other'words, ejecting or looking action could be eliminated from the present device without departing from the spirit and scope of the invention.

What I claim as my invention is 1. A printing roller having an opening therein, means closing said opening, a plural and this applicat idn filed July 15,"

00k portherein, means closing said opening, a plurality of stamp-units having a suitable recess therein slidably mounted in said roller, a lockinglug secured to said closing means and adapted to engage in said recess, an ejecting lug secured to said closing means and adapt ed to engage the end of said stamp-units, both of said lugs being simultaneously actuated to perform their respective duties, substantially as described.

3. A printing roller having an opening therein, means closing said opening, a plurality. of stamp-units slidably mounted in said roller, means fixedly engaging one of I i said stamp-units, and means actuated by said closing means to unlock and eject the other stamp-unit, substantially as described.

4. A printing roller having an opening therein, means closing said opening, a plurality of stamp-units mounted therein, an ejecting lug secured to said closing means and adapted to engage said stamp-units, substantially as described.

5. A printing roller, a plurality of stampunits slidably mounted in said roller means to automatically lock and unlock said stampunits, and means to automatically move out- Ward said stamp-units, said means being simultaneously actuated to perform their respective duties, substantially as described.

In testimony whereof I afiix my signature.
